They're equivalent. 1 J is equal to 1 Newton*1 meter (N*m), and a Newton is equal to a kilogram times a meter per second squared (kg m/s2). Therefore, substituting kg m/s2 for the Newton, and multiplying it by a meter, a Joule is a kg m2/s2. If it's Joules per kg, then it's (kg m2/s2)/kg, and the kg unit on the top and the bottom cancel each other out. You're left with m2/s2!

The relationship between energy per unit mass (J/kg) and energy per unit area (m^2/s^2) depends on the specific context. In general, energy per unit mass represents the energy content of a material, while energy per unit area represents the energy density at a point in space. The two quantities are related through the distribution of energy within a specific system or medium.

What is the unit of measurement used to measure magnetic fields?
Which combination of units can be used to express the magnetic field? Answer kg m2/Ckg s/C2N m2/Ckg/(C s)kg m/(C s2)
What is the kinetic energy of a 1.40 kg discus with a speed of 22.5 m. per s?
the kinetic energy of a non-rotating object of mass mtraveling at a velocity v is ½mv².KE = 1/2*m*v*vKE = 1/2*(1.4 kg)*(22.5 m/s)*(22.5 m/s)KE = (0.7 kg)*(506.25 m2/s2)KE = 354.375 kg*m2/s2KE = 354.375 Joules
Does Pa mean Pounds of Pressure?
Pa is an SI (metric) unit of pressure. 1 Pa - 1 kg/(m-s2) or 1 N/m2. N is Newton, which is 1 kg m/s2. English units of pressure can be psi (pounds per square inch, or lbs/in2), psf (pounds per square foot, lbs/ft2) , or some other unit of force divided by an area. Pascal (unit)
What force (in newtons) must a baseball bat exert on a baseball with a mass of 0.143 kg to give the ball an acceleration of 8500 meters per second squared?
(0.143 kg) (8500 m/s2) = 1215.5 N
Determine the potential energy of an object resting at 854 meters and has a mass of 17.8 kg?
The potential energy of the object can be calculated using the formula: Potential energy = mass * gravity * height. Given a mass of 17.8 kg, gravity is approximately 9.8 m/s^2, and the height is 854 meters, the potential energy can be calculated as PE = 17.8 kg * 9.8 m/s^2 * 854 m = 147067.24 Joules.
Is joule per kilogram equal to meter per second?
No, joule per kilogram is the unit of specific energy, while meter per second is the unit of speed or velocity. They are not equivalent and represent different physical quantities.
What is a SI base unit?
A Joule in SI base units is: 1 kg · m2/s2
What unit is in SI base unit?
A Joule in SI base units is: 1 kg · m2/s2
HOW much is 1 mega pascal in kg?
1 MPa = 1000000 N/m2 and 1 N = 1 kg*m/s2
Is one kilogram is equal to one joule per second?
No, though you could have: 1 kg = 1 J s2/m2. To see this checks out, just consider the following equations: 1. force = mass x acceleration, thus 1 N = 1 kg m/s2. 2. work = force x distance, thus 1 J = 1 kg m2/s2.
What is the unit of measurement used to measure magnetic fields?

What is the kinetic energy of a 1.40 kg discus with a speed of 22.5 m. per s?
the kinetic energy of a non-rotating object of mass mtraveling at a velocity v is ½mv².KE = 1/2*m*v*vKE = 1/2*(1.4 kg)*(22.5 m/s)*(22.5 m/s)KE = (0.7 kg)*(506.25 m2/s2)KE = 354.375 kg*m2/s2KE = 354.375 Joules
What are the basic united?
The fundamental base units are:Distance: A measure of length (the SI unit is the meter,m)Mass: A measure of matter (the SI unit is the kilogram, kg)Time: A measure of duration (the SI unit is the second, s)Charge: A measure of an objects ability to electrically interact (the SI unit is the coulomb, C)Temperature: A measure of average particle translational motion in a system (the SI unit is kelvin, K)Amount of substance: A measure of quantity (the SI unit is the mole, mol)Luminous Intensity: A measure of the amount of light emitted in a direction per unit solid angle. While one could argue that this is a derived unit, it is still listed as a fundamental unit in the SI system of units (the SI unit is the candela, cd)Derived quantities are a function of some combination of the fundamental base quantities units listed above. Some derived quantities and their corresponding units include:Frequency: 1/sArea: m2Volume: m3Velocity: m/sAcceleration: m/s2Momentum: kg*m/sNewton: kg*m/s2Pressure: kg*m/(s2*m2)Work: kg*m2/s2Energy: kg*m2/s2Power: kg*m2/s3Voltage: kg*m2/(s2*C)Resistance: kg*m2/(s*C2)Capacitance: kg*m2/s2Inductance: kg*m2/C2
How much does 10mm toughened glass weigh in kilo newton per square meter?
25 kg/m2 is a density of a toughened glass with 10 mm thick. If you want convert that measure into kN, then multiply by the factor "g" that is gravity (9.81 m/s2) and you get 25 x 9.81 = 245.25 kN/m2.
How much force is needed to accelerate a 3 kg mass at a rate of 4 m per second squared?
F = m A = (3 kg) (4 m/s2) = 12 kg-m/s2 = 12 newtons
Newtons law of universal gravitation is represented by F GMm r2 Here F is the gravitational force exerted by one small object on another M and m are the masses of the objects?
(kg.m/s2) = (G.kg2/m2) G = (kg.m3)/(s2.kg2) = m3 / (s2.kg)
Suppose you catch a salmon with a mass of 5kg. If all of its mass could be converted into energy how many Joules of energy would it produce?
It is Einstein's familiar E = mc2 that we use here. We know that c = 299,792,458 m/s and that c2 = (299,792,458 m/s)2 Got a 5 kgy fish to convert to energy? Let's do that. Using the International System of Units, joules are the units used to measure energy, kilograms are the units used for mass, and meters per second are used for speed. Note that 1 joule equals 1 kg-m2/s2. In unit-specific terms, E (in joules) = m (in kilograms) multiplied by (299,792,458 m/s)2. Let's begin by rounding cto 3 x 108 m/s to make things a bit simpler. That will give us a c2 of about 9 x 1016 m2/s2 and where 1 m2/s2 is a joule. E = mc2 and E = 5 kg times 9 x 1016 m2/s2 = 4.5 x 1017 kg-m2/s2 or 4.5 x 1017 joules of energy.
